fix: resolve 'Current ask promise was ignored' error in multi-file diffs

- Modified Task.ts ask() method to return placeholder responses for partial updates instead of throwing errors
- Improved error handling in multiApplyDiffTool.ts with better logging and user feedback
- Added proper error recovery for batch diff approval failures
- Prevents disruption of multi-file concurrent diff operations

Fixes #8046
